The case records of 50 consecutive male patients aged 40 years or under who were investigated by selective coronary arteriography after myocardial infarction were reviewed. Fourteen patients had normal coronary vessels and 36 patients had significant occlusive disease. Eighteen were considered to be in need of surgical treatment. The features of myocardial infarction on the ECG were less marked in the group of patients with normal coronary arteriograms. Many of these patients were asymptomatic and had complete resolution of the ECG changes. As well as having normal coronary arteries, many also had normal left ventricular angiograms. Cigarette smoking was very common in the whole group, 86 per cent of patients being moderately heavy cigarette smokers. Five of the 14 patients in the ‘non-occlusive’ group were non-smokers and only two of the 36 patients in the ‘occlusive’ group were non-smokers (P<0.01). The fasting serum cholesterol was significantly lower in the ‘non-occlusive’ group than in the ‘occlusive’ group. There was no significant difference between the two groups regarding blood pressure, family history of ischaemic heart disease, obesity or alcohol consumption. There was, however, a high incidence of heavy alcohol consumption amongst patients who subsequently required coronary artery surgery. Many of the patients in the ‘non-occlusive’ group were considered to have had smaller, more localised myocardial infarctions and a lesser degree of coronary disease which may not be detected by coronary arteriography. Others, with more widespread cardiac damage, could be explained on the basis of thrombosis and subsequent recanalisation.

Abstract Background Cardiac magnet resonance (CMR) T1 mapping allows the quantitative characterization of the severity of tissue injury and predict functional recovery in acute myocardial infarction (AMI). Purpose The study aimed to investigate whether native T1 and ECV of infarct myocardium are influenced by microvascular obstruction (MVO) and have predictive value for adverse left ventricular (LV) remodeling post-infarction. Method A cohort of 54 patients with successfully reperfused STEMI underwent CMR imaging at a 3T scanner in AMI and 3 months post-infarction. Native T1 data was acquired using a modified Look-Locker inversion recovery (MOLLI) sequence, and ECV maps were calculated using blood sampled hematocrit. Manual regions-of-interest were drawn within the infarct myocardium to measure native T1 and ECV (native T1infarct and ECVinfarct, respectively). MVO identified as a low-intensity area within the infarct zone on LGE was eliminated. Results MVO was present in 36 patients (66.67%) in AMI. ECVinfarct in patients with MVO was different from those without (58.66±8.71% vs. 49.64±8.82%, P=0.001), while no significant difference in T1infarct was observed between patients with and without MVO (1474.7±63.5ms vs. 1495.4±98.0ms, P=0.352). ECV correlated well with the change in end-diastolic volume (all patients: r=0.564, P&lt;0.001) and predicted LV remodeling in patients with and without MVO (rMVO absent = 0.626, P=0.005; rMVO present = 0.686, P&lt;0.001; all patients: r=0.622, P&lt;0.001); Native T1 was only associated with a 3-month change in LV end-diastolic volume (rMVO absent= 0.483, P=0.042) and predicted LV remodeling in patients without MVO (rMVO absent = 0.659, P=0.003). Furthermore, ECV had an association with LV remodeling (β=0.312, P=0.007) in multivariable logistic analysis. Conclusion Absolute native T1 in infarct myocardium might be affected by MVO but ECV isn't. ECV could predict LV remodeling in MI patients with and without MVO, while native T1 predict it in MI with MVO absent. Funding Acknowledgement Type of funding source: Public hospital(s).

Abstract Background Left ventricular negative remodelling after ST-segment elevation myocardial infarction (STEMI) is considered as the major cause for the poor prognosis. But the predisposing factors and potential mechanisms of left ventricular negative remodelling after STEMI remain not fully understood. The present research mainly assessed the association between the stress hyperglycaemia ratio (SHR) and left ventricular negative remodelling. Methods We recruited 127 first-time, anterior, and acute STEMI patients in the present study. All enrolled patients were divided into 2 subgroups equally according to the median value of SHR level (1.191). Echocardiography was conducted within 24 h after admission and 6 months post-STEMI to measure left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD). Changes in echocardiography parameters (δLVEF, δLVEDD, δLVESD) were calculated as LVEF, LVEDD, and LVESD at 6 months after infarction minus baseline LVEF, LVEDD and LVESD, respectively. Results In the present study, the mean SHR was 1.22 ± 0.25 and there was significant difference in SHR between the 2 subgroups (1.05 (0.95, 1.11) vs 1.39 (1.28, 1.50), p < 0.0001). The global LVEF at 6 months post-STEMI was significantly higher in the low SHR group than the high SHR group (59.37 ± 7.33 vs 54.03 ± 9.64, p  = 0.001). Additionally, the global LVEDD (49.84 ± 5.10 vs 51.81 ± 5.60, p  = 0.040) and LVESD (33.27 ± 5.03 vs 35.38 ± 6.05, p  = 0.035) at 6 months after STEMI were lower in the low SHR group. Most importantly, after adjusting through multivariable linear regression analysis, SHR remained associated with δLVEF (beta = −9.825, 95% CI −15.168 to −4.481, p  < 0.0001), δLVEDD (beta = 4.879, 95% CI 1.725 to 8.069, p  = 0.003), and δLVESD (beta = 5.079, 95% CI 1.421 to 8.738, p  = 0.007). Conclusions In the present research, we demonstrated for the first time that SHR is significantly correlated with left ventricular negative remodelling after STEMI.

Objective Ischemic mitral regurgitation is a predictor of heart failure resulting in increased mortality in patients with chronic myocardial infarction. It is uncertain whether the presence of papillary muscle (PM) infarction contributes to the development of mitral regurgitation in patients with chronic myocardial infarction (MI). The aim of the present study was to assess the correlation of PM infarction depicted by MRI with mitral regurgitation and left ventricular function. Methods and Materials 48 patients with chronic MI and recent MRI and echocardiography were retrospectively included. The location and extent of MI depicted by MRI were correlated with left ventricular function assessed by MRI and mitral regurgitation assessed by echocardiography. The presence, location and extent of PM infarction depicted by late gadolinium enhancement (LGE-) MRI were correlated with functional parameters and compared with patients with chronic MI but no PM involvement. Results PM infarction was found in 11 of 48 patients (23 %) using LGE-MRI. 8/11 patients (73 %) with PM infarction and 22/37 patients (59 %) without PM involvement in MI had ischemic mitral regurgitation. There was no significant difference between location, extent of MI and presence of mitral regurgitation between patients with and without PM involvement in myocardial infarction. In 4/4 patients with complete and in 4/7 patients with partial PM infarction, mitral regurgitation was present. The normalized mean left ventricular end-diastolic volume was increased in patients with ischemic mitral regurgitation. Conclusion The presence of PM infarction does not correlate with ischemic mitral regurgitation. In patients with complete PM infarction and consequent discontinuity of viable tissue in the PM-chorda-mitral valve complex, the probability of developing ischemic mitral regurgitation seems to be increased. However, the severity of mitral regurgitation is not increased compared to patients with partial or no PM infarction. Key points  Citation Format

We retrospectively and prospectively studied 835 patients with acute myocardial infarction (AMI) under the age of 45 and older. Depending on age, patients were divided into two groups: < 45 years and ≥ 45 years. In 189 patients under 45 years of age, the main risk factors leading to the development of ST-elevation myocardial infarction were male sex (OR 6.58; 95 % CI (2.64–16.41), smoking (OR 2.02; 95 % CI (1.44–2.82) and family history of premature coronary artery disease (OR 1.75; 95 % CI (1.21–2.54). According to coronary angiography, AMI patients under 45 years of age in most cases showed no hemodynamically significant coronary vessels damage and had a different course of AMI caused by other reasons – aneurysms of the coronary arteries, muscle bridges, coronary spasm, spontaneous dissections. It was found that 10 % of young patients who did not have obstructive lesions of coronary vessels, according to magnetic resonance imaging (MRI) had focal myocarditis. However, it is noted that in patients under 45 years of age, the presence of familial hypercholesterolemia (FH) may affect the development of AMI. Thus, according to the DLCNS criteria, FH was more frequently reported in young patients than in patients older than 45 years (7.34 % vs 1.32 % (p<0.05)). Hospital course of AMI in young adults was more favorable, with fewer complications. Data from studies of flow-dependent vasodilation have shown that young patients have worse endothelial function on the 1st day of AMI (p=0.043), but better recovery of it in the dynamics of observation. However, in young patients, early (day 7, p=0.029) and late (day 90, p=0.041) left ventricular dilatation was more commonly reported compared with older patients. According to the MRI data on day 1 and in the dynamics (90 days), it was found that, despite the higher prevalence of AMI, young patients have better recovery of contractile myocardial function. The arrhythmogenic substrate (according to late ventricular potential) for life-threatening arrhythmias was more commonly recorded in the older age group at the beginning of the development of AMI, but it was detected with the same frequency in both groups during prolonged observation (6–12 months). Despite better survival and fewer complications during long-term follow-up (4.9 years on average), the greatest impact on the development of the combined endpoint (cardiovascular death / recurrent myocardial infarction / stroke) and death from any cause was made by the patients’ age up to 35 years (best prognosis), concomitant hypertension (worsens prognosis) and low left ventricular ejection fraction (increases complications). The study indicates the possibility of implementing a secondary prevention system in AMI patients of young age through careful (active) observation and control of adherence to treatment and the adequacy of its implementation.

Background: Prior studies show light to moderate alcohol use is associated with reduced mortality and cardiovascular events, whereas heavy use increases mortality and cardiovascular risks. The association of alcohol use and post-myocardial infarction (MI) symptoms is unknown. We explored the association between alcohol use and risk of having angina 1 year after an MI. Methods: Upon enrollment in the 19-center prospective PREMIER registry, acute MI patients (n=2481) were asked about alcohol use. Angina (any vs. none) was assessed at 1 year with the Seattle Angina Questionnaire. The association of alcohol use and 1-year angina was modeled using a hierarchical multivariable modified Poisson regression model. Results: Overall, 47% reported never drinking and others reported having the following # of drinks/day: 42% < 1; 6% 1 to 2; 3% > 2 to 4; 2% > 4. After adjusting for demographic, clinical, and treatment variables, patients that reported never drinking were 45% more likely to have angina than moderate drinkers (1 to 2 drinks/day). However, > drinks/day was associated with an 81% greater risk of angina than moderate alcohol use. Those drinking < 1 drink/day or > 2 to 4 per day had similar angina risk compared to moderate drinkers. Results did not vary by gender (p > .05 for interaction). Conclusions: This study extends prior evidence of a dose-dependent relationship between alcohol use and other cardiovascular benefits/risks to post-MI angina. Moderate alcohol consumption (1 to 2 drinks/day) was associated with reduced risk of angina 1 year after MI compared to abstinence or heavy alcohol consumption. Excessive alcohol use (>4 drinks/day) was associated with increased risk of angina.

Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

The Impact

ObjectiveThe impact on cardiac function of collaterals towards a concomitant chronic total coronary occlusion (CTO) in patients with ST-elevation myocardial infarction (STEMI) has not been investigated yet. Therefore, we have evaluated the impact of well-developed collaterals compared with poorly developed collaterals to a concomitant CTO in STEMI.Methods and resultsIn the EXPLORE trial, patients with STEMI and a concomitant CTO were randomised to either CTO percutaneous coronary intervention (PCI) or no-CTO PCI. Collateral grades were scored angiographically using the Rentrop grade classification. Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic volume (LVEDV) at 4 months were measured using cardiac magnetic resonance imaging. Well-developed collaterals (Rentrop grades 2–3) to the CTO were present in 162 (54%) patients; these patients had a significantly higher LVEF at 4 months (46.2±11.4% vs 42.1±12.7%, p=0.004) as well as a trend for a lower LVEDV (208.2±55.7 mL vs 222.6±68.5 mL, p=0.054) when compared with patients with poorly developed collaterals to the CTO. There was no significant difference in the total amount of scar in the two groups. Event rates were statistically comparable between patients with well-developed collaterals and poorly developed collaterals to the CTO at long-term follow-up.ConclusionsIn patients with STEMI and a concomitant CTO, the presence of well-developed collaterals to a concomitant CTO is associated with a better LVEF at 4 months. However, this effect on LVEF did not translate into improvement in clinical outcome. Therefore, the presence of well-developed collaterals is important, but should not solely guide in the clinical decision-making process regarding any additional revascularisation of a concomitant CTO in patients with STEMI.Clinical trial registrationNTR1108.

Background—Uncertainty exists about the extent and consequences of a return to alcohol consumption after liver transplantation for alcoholic liver disease (ALD).Aims—To determine the prevalence and consequences of alcohol consumption in patients transplanted for ALD.Methods—A retrospective case controlled study of all patients transplanted for ALD at the Queen Elizabeth Hospital, Birmingham, between 1987 and 1996.Results—Seventy patients with ALD were transplanted, of which 59 survived more than three months; 56 were interviewed. Twenty eight had consumed some alcohol after transplantation; for the nine “heavy drinkers” (HD), the median time to resumption of alcohol intake was six months and for the 19 “moderate drinkers” (MD) it was eight months. There was no significant difference in episodes of acute rejection or compliance with medication between those who were abstinent, MD, or HD. Histological evidence of liver injury was common in ALD patients who had returned to drink. Mild fatty change was found in 1/11 biopsy specimens from abstinent patients but moderate to severe fatty change and ballooned hepatocytes were seen in 3/5 MD and 2/5 HD specimens. Two HD patients had early fibrosis. One HD patient has died of alcohol related complications.Conclusions—Moderate to heavy alcohol consumption occurs in patients transplanted for ALD. Patient recall of abstinence advice is unreliable, and patients return to alcohol mainly within the first year after liver transplantation. Return to alcohol consumption after liver transplantation is associated with rapid development of histological liver injury including fibrosis.
